We’ve still got two weeks to go before Transformers: Revenge of the Fallen opens in theaters, but the Hollywood is tracking the film closely and all signs point to a huge debut.

It opens on a Wednesday — June 24th — so it won’t break the three-day opening record that The Dark Knight set with $158 million last summer.  But it will almost certainly make more than that over its first Wednesday to Sunday span.  Rival studios are pegging the debut at $175-180 million, while Paramount itself is aiming for around $160 million.

The sky’s the limit, really.  Today, Deadline Hollywood Daily reported that ROTF is accounting for 21% of all online ticket sales.  And, again, that’s two weeks before the movie comes out.

Paramount was smart to choose June 24th as its opening day.  Its second weekend will be Fourth of July weekend, and while moviegoers tend to stay home on July 4th itself, they heavily go to the movies in the surrounding days.  That means Revenge of the Fallen’s second-weekend drop might be soft compared with other summer blockbusters like Wolverine (which dropped 69%) and Terminator Salvation (which dropped 61%).
